The Vitamin D Testing market has experienced significant growth in recent years due to the rising awareness of the health impacts of vitamin D deficiency. Research highlights that approximately 1 billion people worldwide suffer from low vitamin D levels, which are associated with a wide range of health issues, including osteoporosis, cardiovascular diseases, autoimmune disorders, and an increased risk of certain cancers. This growing awareness has led to a heightened demand for reliable and accurate testing solutions, particularly in regions where deficiency rates are high.
